MECHANICAL TALLY.

Specification of Letters Patent.

Patented Juiy 9,' 1918.

Application filed May 4, 1917; Serial No. 166,300.

To all whom it may concern:

Be it known that I, EUGENE D. BALDWIN, a citizen of the United States, residing at East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in a Mechanical Tally; and I do hereby declare the following to be. a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertaiiis to make and use the same, refer- -ence being had to the accompanying drawings, and to characters'of .reference marked thereon, which forni a part of this specification.

Thel present invention relates, generally, to a pocket counting device or tally keeper; and the invention has reference, niore particularly, to a simple, cheap, compact and easily ope ated tally keeper or counting device which may lie-readily carried in the pocket of the user.

The invention has forits principal object to provide a very simple and compact construction of mechanical `counting or tallying device providingr a comparatively large total counting capacity notwithstanding its small bulk, and which may be a very simple movement while in the hand of the user.

The invention has for a further object'to provide a very simple and easily operated resetting or wipe-out mechanism for returning the counting mechanism to initial counting relation.

Other objects of 'the present invention, not at this time more particularly enumerated, will be clearly understood from the following detailed description of the same.

lith the various objectsof my present in view, the same consists, primarily inthe novel construction of counting or tallying device hereinafter set forth; and the invention consists, further-A more, in the novel arrangements and combinations of the various devices and parts,

as well as in the details of the construction of said devices and parts, all of which 'will be hereinafter more lfully described, and then finally embodied in the claims appended hereto.

The invention is clearly illustrated in the accompanying drawings, in which Figure l is an obverse face view of the plate novel counting or tallying device., and Fig. 2 is a reverseface view of the saine.

Fig. 3 is a reverse face view of the device, with tlie cover of the casing removed to show the interior mechanism; and Fig. et is an obverse face View of the saine with lthe casing shown in section and disclosing the interior mechanism, both of said views being drawn on an enlarged scale.

Fig. 5 is a transverse section of the device, taken on line in said Fig. 3, looking in the direction of the arrow a; and Fig. 6 another detail transverse section of the same, taken on line 6--6 in said Fig. 3, looking in the direction' of the arrow y.

Similar characters of reference are eniployed i'n all of the hereinabove described views 'to indicate corresponding parts.

Referring now to said drawings, the reference character l indicates the face wall of a casing, 2 the marginal side walls thereof, and 3 the cover-plate thereof, which is its ends, with an annular separating-flange 8. Vertically movable through said hub 5 is a stop-pin 9, the outer end of which is normally engaged in a receiving socket l0 formed in the inner surface of said face wall l` of the casing, said stop-pin 9, when so engaged tending to normally retain said carrier-hub 5 against rotary movement. Said .stop-pin'is yieldably maintained in engagement with said receiving-socket l() by means of a'compression spring 1l, mounted against the inner end of said stop-pin, between the same and the inner side of said cover- Mounted so as to rotate upon said carrier-liub 5,at one side of said separatinglangeB, between the latter and said face wall l of saidl casing, is a unit counting wheel 12. Said unit counting wheel 1'2 is provided on its periphery with fifty transmission teeth 13, one of which, indicated by the reference character 14, constitutes a carrying-tooth and vwhich is constructed to be of greater depth than its vfellow teeth.

Fixed upn the outer facev of said unit v counting wheel so as to be rotated therewith,

is a number-disk 15, preferably madeof white Celluloid, or some such material, and upon which are inscribed the unit counting numerals as shown. said casing is provided with a suitably positioned opening or window 16, through which, upon operation of the device, the said unit counting numerals are successively disclosed as the count or tally is' proceeded with.

Mounted so as to rotate upon said carrierhub 5, at the opposite side of said separating-iaiige 8, between the latter and said cover-plate 3 of said casing, is a fifty counting wheel 17.' ,Said iifty counting wheel is provided on itsperiphery with fifty transmission teeth 18. Said fifty counting wheel 17 is smaller in diameter than said unit counting wheel 12, so that the teeth of -the latter are spaced concentrically within or to the rear of the series of teeth.`0f .the latter, but in radial alinementtherewith. Fixed upon the outer face of said fifty counting wheel, so as to be rotated therewith, is a number-disk 19, preferably made of white Celluloid, or some such material, and upon which are inscribed counting numerals indicating hundreds as shown.`

Said cover-plate 3 of said casing is provided with a suitably positioned opening' or window 20, through which, upon the operation of the device, the said hundreds counting numerals are successively disclosed as the count or tally is totaled thereby. The total tally, as recorded by said hundreds counting numerals, is maintained by means of fixed tens numerals 00 and 50 which are inscribed on the exterior of said cover-plate 3 adjacent to or on the right hand margin of said opening or window 20, and which combine with the hundreds counting numerals to give the total amount of the tally in hundreds and tens The means for preventing back-lash or improper directional movement or rotation of the respective counting wheels 12 and 17, comprises a spring-arm 21', the same being secured by a rivet 22, or otherwise, to the inner side of said marginal side walls 2 of said casing. The downwardly projecting end of said arm 21 is bifurcated to provide a pair of inwardly projecting spring dogs, 23 and 24 respectively, the free endsof which respectively engage the teeth of said coiinting-wheels so as to obstruct backward movement of the latter, while yielding of a ficieit width as to adapt the same to engage simultaneously the teeth of both counting-J Said face wall l of v ment with one of the fastening screws 4, or

an equivalent means, limits the upward movement of the same, and determines its initial position. Said. pawl is controlled by an obliquely disposed pull-spring 31, one end of which is anchored over an anchorstud 32 aflixed to and projecting` transversely fromthe inner side of said face wall 1 of said casing, and the other end of which is anchored over a coupling stud 33 projecting laterally from the body of said pawl. Said pull-spring 31 serves not only to retract said push-pawl after'the downward operative movement of the saine, but also serves," by reason of its-oblique disposition, to constantly pull said pawl toward the counting wheels, so as to maintain its nosing 26 in operative relatioiifto and engagement with the teeth of said counting-wheels, since such oblique pull of the spring tends to move the pawl laterally toward the countingwheels while at the same time moving the saine upward longitudinally.

In their initial positionthe respective counting-wheels 12 and 17 are so positioned as to expose through the openings or Win-- dows 16 and 20 their zeros. The zero of the fifty counting wheel is initially opposite the tens zeros inscribed on the coverplate adjacent to the window, 20. I-n using the counting ortallying device., the pushpawl 25 is pressed downward into the casing, and thereby the nosing 26, in engagement with the teeth of the counting wheel 12 moves the 'same forward one interval, thus causing the unit l to appear in the window 16. The pawl is then released so that the pull-spring 31 can retract the saine to initial position. This operation is repeated in counting or tallying each unit until the numeral 49 appearsA in the window 16,

whereupon the push-pawh when retracted to initial position, engages by its nosing 26 the carrying tooth 14. Since the said carrying tooth 14 has a depth greater than its fellows, the lateral inward swinging movement' of the pawl nosingis increased by engagement therewith so that said nosing isf thereby permitted to engage simultaneously-r a tooth 18 of the fifty counting wheel 17. When the push-pawl 25 isf now pushed downward it rotates the unit wheel ll2 Aone interval, thus completing therotation thereof and completing a count or tally of fifty, and at the same time rotates the fifty counting wheel one interval. It thus causes the zero of the unit counting wheel 12 to again appear at the window 16, while the zero of the fifty counting wheel 17 moves forward one interval and alines itself with the tens indication 50 inscribed on the cover-plate 3 adjacent to the window 20, thus indicating a total .count of fty. As the operation of tallying or counting is continued, and the unit wheel` again completes a revolution indicatingV the counting of an additional fifty units, the fifty counting wheel 17 by virtue of the above`described carrying operation is again moved one interval, this movement causing the Zero thereof to move away from the window 20 and out of registration with the tens indication 50 inscribed on the cover-plate 3,'while the numeral l of the fifty counting-wheel is disclosed through the window 20 and registered with the tens indication 00 inscribed on'the cover-plate 3, thus indicating a total count or tally of 100. And so, these operations are continued until the fifty counting wheel has completed its revolution, whereby a total. tally or count of CTI 2500 brings the wheels back to normal initial starting. points.4 It will thus be seen .that the unit counting wheel moves or rotates at the ratio of fifty to one relative to the fifty counting wheel. ratio is preferable for ordinary use and limits the capacity of tot-al registered count or tally to 2500, I do not wish myself to be understood as limiting my invention to such ratio, as the same may be altered with,- out departing from the principles of my invention, and the ratio of movement of the respective counting wheels is dependent only on the number of teeth with which the unit wheel is provided, and,owithin practical limits, this may be varied on the decimal basis from 5 to 100. If the unit wheel had v5 teeth its ratio of movement relative to the other wheel would be five to one, and a very small total tallying capacity would result whereas if the unit wheel had 100 teeth its ratio of movement relative to the other wheel would be one hundred to one, and a comparatively large total tallying capacity would result.

The means for wiping out the total count or tally and resetting the device to initial counting position comprises the following elements: Connected with said spring-arm 21 is an upwardly projecting end 34, from the inner side of which projects inwardly a positioning pin 35. Connected with the outer side of said portion 34 of the springarm 21 is an outwardly projecting pushbutton 36. Connected with the one of the teeth of said unit wheel 12 is a stop-pin 37. Slidably mounted in openings provided in notch curving inwardly to meet tangentially lthe circumference of said carrier-hub. One

While 'such a providing a shoulder 40 at one end, the back 41 of said notch curving inwardly to4 meet tangentially the circumference of said carrier-hub. Inlike manner, formed in the hub-portion 17 'of said fifty counting wheel 17 is a similar notch providing a shoulder 42 atonel end, the back 43 of said of said dogs 3S engages operatively the shoulder 40 of said unit wheel 12, and the other dog engages operatively the shoulder 42 of said fifty counting wheel 17. Projecting from and secured to that journal stud 0 of said carrier-hub 5 which projects through the cover-plate 3 is a screw-threaded shank 44 upon which is secured a turningknob 45. When it is desired to reset the counting wheels,- the push-button 36 is pushed inwardly. This flexes inwardly the portion 34 of the spring-arm 21 and thrust inward the positioning pin 35. Now the turning-knob 45 is utilized to rotate the carrier-hub 5, and the movement of said carrier-hub is imparted to said counting-wheels 12 and 17 by the engagement with the respective shoulders 40 and 42 of the dogs 3S, consequently rotating the said counting wheels until the stop-pin 37 is arrested by engagement with said positioning pin 35 which has been interposed in its path. Then the carrier-hub 5 is thus rotated the stoppin 9 rides out of the receiving socket 10 105 and moves around with the hubuntil the same completes its rotation, whereupon it again is forced by its spring into said receiving-socket. lVhen the counting` wheels are arrested by engagement of the stop-pin with the positioning pin the same' have been returned to initial counting position. lVhen, during the normal counting movements of the counting wheels, the same rotate upon the stationary carrier-hub 5, the tangential backs 41 and 43 of the respective notches of the same rideover the dogs 33,and force the same backward'ly into the carrier-hub,

so it will be readily apparent that said dogs 38 do not interfere with the normal rotation 120 of said counting-wheels upon the carrier hu'b when the latter is stationary.

I am awarethat some changes may be made in the various arrangements andv combinations of the severaldevices and parts, aswell as in the details of the construction of the same, without departing from the' scope of my present invention as defined in the appendedclaims. Hence, I do not limit my invention to the exact arrangements 130 and combinations of the various devices and parts as set forth in the foregoingsp'ecification, nor do I confine myself to the exact details of the construction of said parts as illustrated in the accompanying drawings.

I claim 1. A mechanical tally comprising a casing', a unit counting wheel7 a total counting wheel, said unit counting wheel and total couiitingwheel being mounted back to back within said vcasing so that the unit count is disclosed through one side of said casing and the total count through the other side' of saidfcasing for independent reading thereof, and. an actuating device for mutually operating said counting Wheels projecting from 'theperiphery of said casing.
